Abstract
The disclosed technology provides ways to suppress or eliminate the effects of roadnoise when performing acoustic leak detection in a wellbore environment. In some aspects, a method of the technology includes steps for receiving acoustic training data, wherein the acoustic training data comprises signals representing acoustic tool contact with a wellbore surface, and generating a suppression model based on the acoustic training data, wherein the suppression model is configured to suppress roadnoise received at a hydrophone array disposed within the wellbore. Systems and machine-readable media are also provided.
